Flumps are one of those sweets everyone from a certain era recognises instantly by shape alone — the twisted, multicoloured marshmallow rope — but knows almost nothing about beyond that. Here's where they actually came from, and if you want to do more with the marshmallow itself, we've covered that separately too.
A Barratt product through and through
Flumps are made by Barratt, one of the oldest names in British sweets, dating back to 1848. Barratt is also behind long-running pick 'n' mix regulars like Dip Dabs, Black Jacks and Fruit Salads, and Flumps sit firmly in that same retro-British lineage — individually wrapped, twisted marshmallow in pink, yellow, white and blue, vanilla flavoured throughout.
Why the twist?
The format was deliberate rather than incidental: a softer, lighter marshmallow than the chewier marshmallow bars that were already on the market, shaped into a long twist specifically so it could be eaten slowly, piece by piece, rather than in one bite. Unlike a lot of retro sweets that have been resized, reformulated or repackaged over the decades, Flumps have stayed close to their original shape and flavour the whole way through.
What we stock
We carry the Barratt Flumps Sweets Box, a full case of 50 individually wrapped 20g packs — well stocked at the time of writing. It's a special-order line for us, so allow around two weeks for delivery at the same price as always. You'll also find it, and the rest of the Barratt range, in our Barratt collection.
If you're after marshmallow ideas beyond the bag
Flumps are marshmallow at heart, and if what you actually want is ways to use marshmallow in baking, hot chocolate or rocky road, we've written a separate guide — Marshmallows Are Not Just for Hot Chocolate — covering that in more depth, including the vegan marshmallow question. This piece is about the Flumps twist specifically, not a repeat of that one.
FAQ
What are Flumps made of?
They're a vanilla-flavoured marshmallow sweet, twisted into a rope shape and individually wrapped. Barratt's own listing states no artificial colours or flavours; for a full ingredients and allergen breakdown, always check the pack.
Why are Flumps twisted instead of just cut into pieces?
The twist shape was designed to make a softer, lighter marshmallow easy to eat slowly, piece by piece — a different eating experience from the chewier marshmallow bars that were around at the time.
How long has Barratt been making Flumps?
Barratt itself dates back to 1848, and Flumps have been part of its range since the 1980s, making them a long-standing pick 'n' mix staple rather than a recent addition.
Do you sell Flumps in stock right now?
Yes, as a full case of 50 individually wrapped packs. It's a special-order line with roughly a two-week lead time.
Is there a recipe guide for using marshmallows like Flumps in baking?
We have a separate guide, Marshmallows Are Not Just for Hot Chocolate, covering rocky road, s'mores and other uses for standard marshmallow — worth a look if that's what you're after, since it's a different topic from the Flumps sweet itself.
